We have bought 9psc Ice 50 esc's with the 4.01 firmware but they lose sinc on 28 and 24 poles motors

Hope Castle wil improve there firmware because this motors are running without any problem on a Mystery 40A ESC with simonK firmware, we bought (for almost Ä1000,00 !!) the Ice 50 ESC's because we wanted a pro solution, but like this they are useless!!

What timing and PWM have you tried? What ICE firmware version number – some versions work better with high pole count motors than others.

The Outrunner PWM option is specifically designed for high pole count motors. Go to the Motor tab and select PWM Outrunner. Then try timing of 0, 1, 2, 3, 4, and 5 to see what works best. A bit of bench testing should bet you up and running.

Also I have noticed that the muntirotor sometimes has a bit of a hard start so start with start power of low. If it does not spin up smoothly then increase the start power until it starts smoothly.

One of the biggest problems that I have seen with multirotors is the tendency to over prop the motor. That will cause problems like loss of sync. Do some bench testing starting with a very small prop and gradually increase until you find a prop that runs well and does not exceed the motor current at 100% throttle. Run it up to full throttle for a couple of minutes to make sure that nothing overheats. A bit of bench testing really pays off so that you will get a reliable setup.

holco I have the MT4008 motors and they lose sync for sure with simonk firmware.

with wiiesc firmware they do not lose sync BUT I lose about 15% of the top end for throttle...

with a standard turnigy plush 30 amp it loses sync unless you are on high timing... and the esc gets super hot... so I think it's pulling 20+ amps

So the question is... is there a firmware (fast) that works properly with these motors? If you set your Castles to high timing it may work for you... but at what cost I wonder? efficiency? power or heat???

Today I tested the 28 poles Dualsky XM5010TE-5 with higher (20) timing on the Ice 50 and now the motor is not loosing sync
Its not perfect yet but its looking better, tomorrow I will test some more settings.

Greetings,

Mario

WOW it sounds like those are very poorly designed motors. Why would anyone want to use such a motor when there are so many excellent motors on the market that never give any problems like that. I really donít understand the purpose in this discussion just too those motors and get something better.

I second that, people think they waste $50 per Chinese motor and somehow that makes them good, when there's pretty much same stuff available for way cheaper.
A few clever Chinese put shiny hologram stickers on old line of motors and now everyone thinks they're awesome. Anyone remember PulsoAVRotoRCTigerMotors all same stuff all made in same factory with a different shininess sticker on it and each one charging $10 more for same thing.
